Detailed Description
In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The first embodiment is as follows: as shown in fig. 1 to 6, a side glue feeding structure of a plastic frame injection mold comprises a core plate 10, a mold core 20 and four sliding blocks 30, wherein the mold core 20 is fixedly installed at the center of the core plate 10 through bolts, the four sliding blocks 30 are slidably installed on the core plate 10 and are respectively located around the mold core 20, the four sliding blocks 30 and the mold core 20 are combined to form a cavity 40, and the sliding blocks 30 are provided with a main branch runner 301, a plurality of secondary branch runners 302 communicated with the main branch runner 301, and a plurality of submarine gates 303 correspondingly communicated with the secondary branch runners 302.
In the first embodiment, for convenience of manufacturing, the glue inlet of the submarine gate 303 is circular or rectangular, please refer to the end shape of the submarine gate material 503 in fig. 5 to 6.
In the first embodiment, the four sliders 30 include two short sliders 31 and two long sliders 32, three sub-runners 302 and three corresponding submarine gates 303 are disposed on the short sliders 31, and five sub-runners 302 and five corresponding submarine gates 303 are disposed on the long sliders 32.
The working principle of the first embodiment is as follows: during injection, the rubber firstly flows into the plurality of secondary runners 302 from the main runner 301, then flows into the submarine gate 303 from the secondary runners 302, and finally flows into the cavity from the submarine gate 303; during demolding, due to the included angle of the submarine gate 303, the rubber frame 50 and the submarine gate material 503 are automatically sheared and separated through the rubber ejection frame 50. As shown in fig. 7, since the glue inlet of the glue frame 50 is arranged on the side surface, the front surface of the glue frame has no glue inlet and is flat without protrusions; as shown in fig. 8, the liquid crystal panel 60 is also flat when attached to the front surface of the bezel 50 by double-sided adhesive.
Example two: referring to fig. 1 to 6, a plastic frame injection mold includes the above side glue feeding structure.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art should not depart from the technical scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should fall within the scope of the present invention.
